ELECTRIC HEATER.

Specification of Letters Patent.

?atented June 11, 1907.

To all whom it may concern:

Be it known that I, Josarn SHERIDAN i REYNoLns, a citizen of the United States, and a resident of Santa Barbara, in the county of Santa Barbara and State of California, have invented a new and Improved Electric Heater, of which the following is a full, clear, and exact description.

My invention relates to electric heaters, 1

my more particular object being to improve the general construction of the heater and more particularly to rovide an improved manner for mounting t e heating Wire.

Reference is to be had to the accompanym drawings formin a part of this specification, in which simi ar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a vertical longitudinal section through one form of heater embodying my invention, the figure showing one of the heatr'esisting plates and its wiring, together with means for supporting-this plate; Fig. 2 is a central vertical section through the heater and showing the two supporting brackets used for sustaining the heat-resisting plates; Fig. 3 is a fragmentar plan showing one form of heat-resisting p ate and the heating wire being applied thereto, the figure showing different stages employed in attaching.

the wire; Fig. 4 is a ongitudinal section through the mechanism shown in Fig. 3;

Fig. 5 is a fragmentary plan of another form of heat-resisting late 111 which the wire is secured by aid of. oles rather than by aid oi slots, as in Fig. 3; Fig. 6 is a central longitudinal section through the mechanism shown in Fig. 5; Fig.7 is a fragmentary plan showing the upper right-hand corner of a heatresisting plate in which the heating wire engages an eyelet used for supporting the plate.

The body of the heater is shown at 7 and is provided with screen walls 8 to facilitate the circulation of air. The body-portion is supported upon legs 10 and is opened at its bottom portions 11. A handle 12v is provided for convenience in lifting the heater around by hand. A plate supporter 13 having the form of a bracket, is mounted upon a block 14 preferably of insulating material, the latter being connected directly with the body portion of the heater. 'lhvo other brackets 15, 16 are mounted upon a plate 17 of insulating material and are out of engagement with each other, bein secured upon the plate by screws 18. These brackets 15, 16

1 are each provided with a binding 0st 19, 19, the latter being insulated from t e body l portion 7 of the heater. lhe bracket 13 is 1 provided with spirally disposed hooks 20 in- 5 tegral therewith. The brackets 15, 16 are provided with spirally disposed hooks 21, 22 5 of the form shown in Fig. 2. A sheet of 1 heat-resisting material, such as asbestos, is provided at one of its edges with a strip 23 of 5 metal bent back upon itself for the urpose of clam ing and supporting one cm of the sheet 5 th with strips 24, 24* of metal separated from each other. The strips 23, 24, 24 are provided with holes 24*, 24, 24 The holes 24 receive the hooks 20 and the holes 2 1-, 24 receive the hooks 2i 22.

The heating wire is shown at 26 and may be connected, as indicated in Fig. l, with its ends. secured to the respective strips 24, ar The sheet 25 is provided with slots 27 cut parallel with each other and disposed obli uely in relation to the general position of the s eet. The heating wire 28 is first formed into a spiral, as shown in the u per portion of Fig. 3 and this spiral is force against the sheet in such a manner that portions of the wire proiect above the sheet, whereas other ortions of it pass through and project from t e opposite side. These last mentioned portions 29 are then bent sidewise, as indicated by dotted lines in Fi 3. in doing this all protruding portions of the wire 28 are flattened directly a ainst the sheet so that the wire is held rigi ly in position u on the latter.

in the form of eat-resisting plate shown in Fig. 5, the material of the sheet is shown at in rows and staggered relatively to each other. A wire 32 is doubled so as. to form loops 33 and these are assed through the holes 30, 31 and bent or cl nched upon the o posite side, as indicated inFig. 6, thus hol ing the wire firmly in position on the plate. In the form shown in Fig. 7 the heat-resist 0 plate appears at 34 and the wire at 35. e latter is connected with a metallic eyelet 36 which engages one of the hooks 21, so as to assist in su ortingthe heat-resisting late.

e slots 27 may be forme merely b cutting the heat-resisting late 25 by aid of a chisel or knife and the oles 30, 31 may be formed by means of a punch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

e other end of the sheet is provided 29 and is provided with holes 30, 31' arranged 1. In an electric heater, the combination of a heat-resisting plate rovided with apertures, and a wire provi ed with portions extending through said apertures and clenched so as to hold said wire in engagement with said plate.

2. In an electric heater, an electrical plate rovided with heatin members, asheet of eat-resisting materia provided at one of its ends with metallic strips separated from each other, said strips having holes for engaging the support, and an electric wire connected with said stri s and secured to said plate.

3. In an e ectric heater, a heat-resisting plate, consisting of a sheet of heat-resisting material, a wire secured thereu on, and a metallic eyelet engaging said wire or the purpose of sup ortins said sheet.

4. I ii an electric heater, a support comprising a plate of insulating material, a pair of members of conducting material mounted thereupon and s aced a art, said members being provided with spira hooks, and binding posts in electrical communication with said members.

5. In an electric heater, a heat-resisting plate of insulating material provided with mutilations, and a wire havingits main portion disposed upon one side of said sheet, said wire belng provided with portions pro'ecting through the mutilations and clenche upon the opposite side of said sheet upon said main portion of said wire so as to hold said wire upon said sheet without sewing it thereto.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
